Championship showdown expands as Boost Mobile AUSX Supercross Grand Final joins the bp Adelaide Grand Final

Australia’s biggest motorsport finale just got even bigger – as the adrenaline-charged BOOST MOBILE AUSX Supercross Grand Final will now be part of the bp Adelaide Grand Final, delivering three-days of high-stakes motorsport action from November 28–30, 2025.

Already home to the final round of the Repco Supercars Championship, the bp Adelaide Grand Final now expands to host the fifth and final round of the 2025 BOOST MOBILE AUSX Supercross Championship. Champions will be crowned in spectacular fashion.

Following the success of last year’s packed crowds within the Victoria Park complex, Supercross returns with a bigger, three-day format featuring world-class racing on a purpose-built track designed for high flying, non-stop, bar-to-bar action.
Supercross will span across all three days of the event:

• Friday:  Practice and Qualifying for premier classes, kicking off the weekend
• Saturday: SX3 and junior 85cc Heat Races, Premier Class SX1 and SX2 Heats + Championship Grand Final races.
• Sunday: SX3 and Junior 85cc Championship Finals to round out the weekend.

This year, fans will have more ways to experience Supercross than ever before. Saturday’s night show — featuring the crowning of the SX1 + SX2 Champions — will be ticketed via Ticketmaster, including the option to secure reserved seating in the Victoria Park Heritage Grandstand for premium viewing.

Existing ticketholders can purchase the reserved seating as an add-on to their ticket, with general admission tickets to the bp Adelaide Grand Final providing inclusive, trackside viewing to both the Repco Supercars Championship and BOOST MOBILE AUSX Supercross Championship action.

For a premium viewing experience of all the Supercross thrills, the VIP Supercross Platform will return in 2025 for the three-hour show on Saturday. Located at the front of the Heritage Grandstand, spectators can enjoy an inclusive food and beverage package trackside with hospitality tickets available [adelaidegrandfinal.com.au/hospitality/boost-mobile-australian-supercross-grand-final-vip/]here.

South Australian Motor Sport Board CEO, Mark Warren said “It is extremely exciting to add more final-round action to the bp Adelaide Grand Final event, with the BOOST MOBILE AUSX Supercross Grand Final set to be a key highlight on 29 November.

“Hosting the Supercars grand final and enhancing our off-track events will create a unique sporting experience for fans nationwide, making the bp Adelaide Grand Final the place to witness champions crowned.

“It’s fantastic to welcome the BOOST MOBILE AUSX Supercross Championship back to the event. Its grand final promises to deliver the all-or-nothing intensity that defines the internationally recognised championship.”

AUSX Managing Director, Kelly Bailey, added “We’re proud to return to the bp Adelaide Grand Final for the ultimate round of the BOOST MOBILE AUSX Supercross Championship. There’s no bigger stage to showcase our sport and this event allows us to be part of Australia’s largest motorsport finale.

“The three-day program and a dedicated Saturday night Supercross program helps us build the scale and energy our championship deserves.”

Riders of the 2025 BOOST MOBILE AUSX Supercross Championship will be revealed soon, but fans can expect a stacked field of the best national and international supercross talent in the line up ready to battle it out for championship glory.

A brand-new track design, partner activations and the full race schedule is to be unveiled in the lead up to the bp Adelaide Grand Final.
